    Abstract: Optoelectronic apparatus includes a substrate and an array of light-emitting elements formed on a semiconductor die and mounted on the substrate, wherein the light-emitting elements are driven by separate, respective conductors, which are formed on the substrate. A controller drives the light-emitting elements selectively by applying drive signals to the respective conductors in order to create a pattern. One or more optical elements are mounted so as to receive light emitted from the array of light-emitting elements and include at least one diffractive optical element (DOE) configured to project the received light from the first optical element so as to create multiple replicas of the pattern, which fan out over a predefined angular range.

    Abstract: Optical apparatus includes a beam source, which is configured to generate an optical beam having a pattern imposed thereon. A projection lens is configured to receive and project the optical beam so as to cast the pattern onto a first area in space having a first angular extent. A field multiplier is interposed between the projection lens and the first area and is configured to expand the projected optical beam so as to cast the pattern onto a second area in space having a second angular extent that is at least 50% greater than the first angular extent.

    Abstract: Imaging apparatus includes an illumination assembly, including a plurality of radiation sources and projection optics, which are configured to project radiation from the radiation sources onto different, respective regions of a scene. An imaging assembly includes an image sensor and objective optics configured to form an optical image of the scene on the image sensor, which includes an array of sensor elements arranged in multiple groups, which are triggered by a rolling shutter to capture the radiation from the scene in successive, respective exposure periods from different, respective areas of the scene so as to form an electronic image of the scene. A controller is coupled to actuate the radiation sources sequentially in a pulsed mode so that the illumination assembly illuminates the different, respective areas of the scene in synchronization with the rolling shutter.

    Abstract: An optoelectronic device includes a semiconductor substrate and a monolithic array of light-emitting elements, including first and second sets of the light-emitting elements arranged on the substrate in respective first and second two-dimensional patterns, which are interleaved on the substrate. First and second conductors are respectively connected to separately drive the first and second sets of the light-emitting elements so that the device selectably emits light in either or both of the first and second patterns.
